A perfect way out of RSI, this is probably the most ergonomic solution for a mundane (and obligatory) task on any computer. What could be better than a mouse that slides effortlessly on to your finger and lets you move the pointer with your fingertips?

The USB Finger Optical 3D mouse does away with the need for any mouse pad and is designed to reduce fatigue. The regular click and scroll buttons are housed on the surface of the mouse. Compatible with Windows OS as well as Mac 9 and above, this pointer has a voltage of about DC 5V.

The only worry could be typing with this thing on a finger. Also scratching stuff might be a bit problematic, if you know what I mean. Available here for $9.99.
